Cartier’s New Special Order (NSO) program gives collectors a rare opportunity to create a watch customized to their specifications. Here’s how it works.Watch collectors are inherently detail-oriented people, often obsessing over the smallest details in a dial, case, or handset. Some collectors wish for a watch that is an amalgamation of design elements from a variety of references, but it’s rare to have an opportunity to see those changes come to life. The Cartier “New Special Order” (NSO) program gives collectors that opportunity. But what is the NSO program? Who had access to it? And how does it work today?How the Cartier NSO Program WorksCartier is the master of watch design, with a massive catalogue of unique case shapes, dials, materials, and configurations. From the curved Cintrée to the asymmetrical Crash, and everything in between, the allure of a Cartier design is unique in the industry. The NSO program gave the opportunity for collectors to collaborate directly with the maison to make fine adjustments to Cartier’s catalog of pieces.
